Yeah, I’ve been looking for these too - I’m building an LC as well as my other box. I’ve sent them an email but I’ve been informed they won’t be getting them back in stock as they have lost their supplier for them. They are still on Panasonic’s site as a current part but the minimum order is 100 (I think). I’ve had no joy finding anyone else selling them yet. Finding motor-faders is like finding a needle in a haystack. The only other ones I’ve found so far have been around £25 each - for 8 faders at that price you may as well just go out and buy a pre-made box. Mouser have some ALPS faders in for…$50 each. Ouch
